PURPOSE: Clinical provider peer review (CPPR) is a process for evaluating a patient's experience in encounters of care. It is part of ongoing professional practice evaluation and focused professional practice evaluation-important contributors to provider credentialing and privileging. Critical access hospitals are hindered in CPPR by having a limited number of providers, shortages of staff resources, and relationships among staff members that make unbiased review difficult. Small departments within larger institutions may face similar challenges...

Introduction. Pneumocystis pneumonia (PCP) is rising in the non-HIV population and associates with higher morbidity and mortality. The aggressive immunosuppressive regimens, as well as the lack of stablished guidelines for chemoprophylaxis, are likely contributors to this increased incidence. Herein, we have explored the underlying conditions, immunosuppressive therapies, and clinical outcomes of PCP in HIV-negative patients. Methods. Retrospective analysis of PCP in HIV-negative patients at Mayo Clinic from 2006-2010...

BACKGROUND: Various clinical and histological factors have helped in predicting the survival of patients with oral squamous cell carcinoma (OSCC). However, there has been a need for more specialized diagnostic and prognostic factors to avoid subjective variation among opinion. Thus, fractal dimension (FD) can be used as an index of the morphological changes that the epithelial cells undergo during their transformation into neoplastic cell. In oral cancer study, nuclear FD (NFD) can be used as a quantitative index to discriminate between normal, dysplastic and neoplastic oral mucosa...

A variety of interstitial Lung Diseases (ILD) have been described in patients with myelodysplastic syndromes (MDS) with possible etiologies including autoimmunity, drug related toxicity, and recurrent infections. A comprehensive study of ILD in MDS patients has not been previously performed. Out of 827 consecutive biopsy proven MDS patients seen at our institution from June 1970-May 2010, 18 (2%) were found to have ILD. There was no statistical significance in baseline characteristics between patients with ILD (ILD +) vs those without ILD (ILD-)...

BACKGROUND: Takotsubo cardiomyopathy (TCM) is an intriguing phenomenon characterized by transient and reversible left ventricular (LV) dysfunction despite angiographically unobstructed coronary arteries. The detailed pathophysiology of stunned, viable myocardium in TCM remains to be determined. Post-extrasystolic potentiation (PESP), the phenomenon of enhanced LV contractility following extrasystole, has been used to assess myocardial viability. METHODS: Utilizing a local database, we identified 74 cases that met the modified Mayo Clinic criteria for TCM between October 2004 and March 2016...

Radial head fractures are common injuries, occurring mostly in active young people 85%. Treatment of the more complex radial head fractures (Mason type III and IV), appear to be challenging and remain a subject of controversy. Replacement of the radial head with a metal prosthesis imitates the stabilizing role of the radial head and has been considered as the treatment of choice. However, long-term results are scarce. We report our mid to long-term (mean 9.4 year) clinical and radiographic results after insertion of a Judet Bipolar Radial Head prosthesis...

The purpose of this study was to review the clinical results of carpal ligaments injuries with scaphoid nonunion. We hypothesized that scaphoid nonunion with carpal ligament injury is associated with clinical result. We retrospectively reviewed 60 cases of -Herbert screw fixation with bone graft for scaphoid nonunions. Scapholunate (SL) and lunotriquetral (LT) ligaments lesions were confirmed by arthroscopy. Approximately half of the nonunion scaphoid cases had carpal ligaments injuries. At final follow-up evaluation, wrist function as evaluated by the Mayo wrist score was excellent in 34 patients, good in 16 patients, fair in 8 patients, and poor in 2 patients...

INTRODUCTION: Neoadjuvant treatment might increase resectability of thymic epithelial tumors (TET). No standardized pathologic grading scheme for tumor response is available. Also, it is unclear whether radiologic treatment response can predict pathologic response. METHODS: Patients with unresectable TET who underwent neoadjuvant treatment before surgery at Mayo Clinic Rochester (1942-2014) were included. The pathologic tumor response grade (TRG) was based upon Mandard-grading (1994) ranging from TRG 1 (no viable tumor) to TRG 5 (no regression)...

BACKGROUND: In the USA, the number of people needing implantable cardioverter defibrillators (ICDs) has grown dramatically. Many ICD recipients will need to undergo a surgical procedure at some point following ICD implantation. Most surgeries involve the use of electrocautery. Currently, the effects of electrocautery-induced electromagnetic interference (EI-EMI) on ICDs are poorly understood. The aim of this study was to study EI-EMI using prospectively collected clinical data. METHODS: We analyzed prospectively collected ICD data from patients undergoing a surgical procedure at Mayo Clinic between 2011 and 2012...

BACKGROUND: Diagnostic evaluation of patients with diffuse parenchymal lung disease (DPLD) is best achieved by a multidisciplinary team correlating clinical, radiologic, and pathologic features. Surgical lung biopsies remain the gold standard for histopathologic diagnosis of idiopathic interstitial pneumonias. Emerging data suggest an increasing role for transbronchial cryobiopsy (TBC) in DPLD evaluation. We describe our experience with TBC in patients with DPLD. METHODS: We retrospectively reviewed medical records of patients with radiographic features of DPLD who underwent TBC at Mayo Clinic, Rochester, Minnesota in June 2013-September 2015...

BACKGROUND: The treatment of complex distal humerus fractures is challenging and is often associated with unsatisfactory results. Anatomic reduction and stable internal fixation is difficult to obtain, especially in elderly osteoporotic patients. For these reasons, total elbow arthroplasty (TEA) has recently evolved as a valid procedure in selected cases following these injuries. The aim of this study was to analyze outcomes of TEA for the treatment of complex distal humerus fractures in 20 low-demanding patients over 65 years of age...

Acute exacerbation (AE) of interstitial lung disease is reported to be developed in not only idiopathic pulmonary fibrosis but also connective tissue disease-associated interstitial pneumonia (CTD-IP). As the significance of AE of CTD-IP has not been so widely recognized, its clinical feature is not fully elucidated. In the present study, we investigated the incidence, clinical features and outcome of AE of CTD-IP. We retrospectively reviewed admitted cases in our department with medical record from 2011 to 2015...
